The Marquette Maritime Museum has been fortunate in assembling the preeminent collection of lighthouse lenses anywhere in the Great Lakes and certainly on a level with the best in America.
Having a 2nd, 3rd, 3 1/2 and 4th order “classical” Fresnel lenses in the same exhibit hall concurrently is unheard of!
When the DB24 airport beacon and modern acrylic systems are included, the visitor can see nearly the entire evolution of lighthouse illuminating systems. All that is missing is a Winslow Lewis lamp (and if anyone has a lead on one, please let our staff know!).
